What is the Test for bulk specific gravity commonly referred to as?

The test for bulk specific gravity is commonly referred to as the "Rice test." This term is named after the engineer who developed the procedure, which is used to determine the specific gravity of hot mix asphalt materials. The Rice test is crucial in asphalt mix design and quality control because it helps assess the volumetric properties of the mixture, influencing decisions on mixture proportions and ensuring the adequate performance of asphalt pavements.

The process involves measuring the mass of a sample in air and then determining its volume by immersing it in water, allowing for the calculation of bulk specific gravity. This specific measure is vital for understanding how much asphalt binder is necessary for optimal performance and how the asphalt will behave under different load and environmental conditions.
